Abstract
Central adiposity is related to insulin resistance and may be the most clinically relevant body fat in children as is the case in adults. This study aimed to determine relationships between child's television viewing (TV), aerobic fitness, diet and central adiposity in 172 prepubertal children (8–9 years). Parents reported child's weekday and weekend TV viewing. Maximal oxygen consumption (VO2max) and one 24‐hour recall assessed fitness and diet, respectively. Dual energy X‐ray absorptiometry was used to measure percent fat mass (%Fat) and central adiposity (FM‐abd). Waist circumference to height ratio (WHtR) was also measured. Aerobic fitness was not related to TV, however, it was negatively related to %FM (r=−0.49, p < 0.01) and FM‐abd (r=−0.41, p < 0.01). Weekday and weekend TV was positively related to FM‐abd (r=0.18, p=0.02 and r=0.20, p=0.01). After adjusting for VO2max and total diet energy density (kcals/g), added sugars (g) positively related to FM‐abd (r=0.18, p=0.03). To further assess central adiposity, children were classified as normal (n=129) or obese (n=43) based on the 0.5 cut off for WHtR. Obese children had significantly higher weekday TV (p=0.03) and consumed higher amounts of added sugars (p=0.02). Our findings suggest that central adiposity is related to increased intake of added sugars independent of aerobic fitness and energy density in prepubertal children.
